In Loving Memory

Terry Wilson

On May 3, 2019, our company’s Founder and Co-owner, Terry Wilson, passed away after battling leukemia, moving on to be with Jesus.

When Terry and Wynell established this business in 1995, they had three primary goals: to shine as a beacon for Christ, to provide for their family, and to create opportunities for their children to support their own families. Terry wholeheartedly achieved these goals and much more.

Known for his selflessness, Terry always prioritized the well-being of those around him—a trait evident in his work. He tirelessly strived to enhance project quality for customers, often staying up late to devise innovative approaches. He generously shared his knowledge with employees, aiming for their success.

Terry’s wisdom and vast expertise are deeply missed. However, his legacy persists through the foundation he laid for Cornerstone. We are committed to upholding his legacy daily, promising our customers an unwavering dedication to delivering our best.

We adhere to the scripture from Colossians 3:23, “As unto the Lord and not unto men,” putting our hearts into everything we do.
